I have listen about it in "Come to Dance" by John Whelan, but i think it is a tune composed by Robin Bullock.
Maybe there is an user that can tell us the truth.
“The Turning of the Screw” ~ C: Robin Bullock
& from John’s album: "Come to Dance"
"The Turning of the Screw" composed by Robin Bullock, published by Nara Music Inc.(BMI)/Wolf Howl Music (BMI)
John Whelan’s ‘band’ includes Robin Bullock and there are several other of his compositions on this recording… And to think I knew John way back when, before he had a wife, children and was born again… He was always a nice lad, and a talented musician too…
I don’t have this album by John Whelan, but I’ve got his other two. Beautiful tune.
